I'm trying the Americans in the 1775-1783 sec. When the game starts, I move reinforcements into the Contiental Army outside of Boston. I leave the army alone, not moving into the city or taking off defensive.
The second month, the British sorty outside of the city and crush my army, but good. Not really historic.
And if I try to move the army to another closeby city, like Providnece, I can defeat the British force that attacks but suddenly another month later a SECOND British army shows up behind my lines.

What the heck is the best thing to do with the Americans at the start here to force the British to leave Boston or defeat them, and not have them break out into the rest of New England?
Also, having a issue with the save games. There seems to be a autosave option that goes right over my manual saves -- even if I change the game name. So I can't go back to a previous turn if something happens.
Help!
